Buffer swaps in ST02 do not relate to swap memory.

A swap occur when the buffer gets full, you need to review the size of the buffer affected, I can tell you that 300.000 is very small for the program buffer.

You need to start playing with the values of the parameters until you find a balance... for example you could raise the program buffer to 400.000 and restart the system if it still produce a lot of swaps then you can raise it to 500.000, etc...

A small number of swaps is not really a problem, but high number of swaps can be in detriment of your system performance.

Double click on the red highlighted swap, now click on current parameters.

Here you can see which parameters designates the memory for this buffer area. Once buffer is exceeded it begins to SWAP.

this is not a bad thing unless you are seeing performance problems. Most performance problems are far deeper than this.

You now need to research the overall memory usage and decide whether to increase the parameter and possibly decrease others.

use ST06 as well for overall usage amounts of swap.

There is much to understand but you can start by reading here:
